Louis de Wecker (29 September 1832 – 24 January 1906) was a French ophthalmologist born in Frankfurt am Main, Germany.
From 1862 he maintained a popular ophthalmology clinic in Paris.
In 1867 he performed an enucleation of the eye of Léon Gambetta.
His name is associated with "de Wecker scissors", which are small sharp-pointed scissors used for intraocular surgery of the iris and lens capsule.
[1] Dr. José Rizal (1861-1896), martyr and national hero of the Philippines, completed his ophthalmological training under Professor Louis de Wecker in Paris in 1885.
